[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to an oil cargo handling device capable of unloading cargo oil in a tanker, and a system for unloading and recovering cargo oil from a stranded tanker and rescuing the stranded tanker. Concerning possible marine tanker rescue ships.

0002

[Prior Art] Generally, when cargo oil such as crude oil in a tanker is unloaded at a discharging port, the pipeline of the tanker moored to the dolphin at the discharging port and the pipeline on the land side are connected via a loading arm. The cargo oil in the cargo oil tank is then unloaded using the unloading device on the tanker side.

[0003] In addition, when refueling at sea between a tanker and another ship, the tanker's pipeline and the other ship's pipeline are connected with a flexible hose, and the tanker's unloading device is used to refuel the tanker and the other ship. Refuel the ship.

As shown in FIG. 4, the tanker unloading device has a pump room 2 partitioned adjacent to a cargo oil tank 1, and a plurality of cargo handling pumps 3 are installed in the pump room 2.
At the same time, these cargo handling pumps 3 and the cargo oil tank 1 are connected via piping 4, and the pipeline 5 connected to the cargo oil tank 1 and the pipeline on the unloading side are connected to a loading arm (both shown in the figure). (not shown), and a plurality of cargo handling pumps 3 are driven to handle cargo oil in the cargo oil tank 1 through a pie line 5 to the above-mentioned unloading side pipeline.

[0005]

[Problems to be Solved by the Invention] By the way, the above-mentioned tanker unloading device has a problem in that the dedicated pump room 2 for installing the cargo handling pump 3 occupies the space inside the ship, so the space for loading cargo oil is compressed. Furthermore, there is a problem in that complicated devices such as a generator and a drive device for driving the cargo pump 3 or a large number of piping must be installed inside the ship.

On the other hand, it is conceivable to install a cargo handling device on the unloading side and omit the unloading device on the tanker side, but it is possible to install a suction pump or the like in the pipeline on the unloading side to remove the cargo oil in the cargo oil tank. However, if the cargo oil tank 1 is deeper than the head pressure equivalent to atmospheric pressure, there is a problem that the cargo oil in the cargo oil tank 1 cannot be completely unloaded.

[0007]The present invention was devised to solve the above-mentioned problems, and one of its objects is to unload cargo oil from a tanker using a cargo handling device on the unloading side. Another object of the present invention is to provide an oil cargo handling device, and another object is to provide a tanker rescue ship capable of recovering cargo oil in a stranded tanker and rescuing the tanker.

[0008]

Means for Solving the Problems In order to achieve the above object, the invention of claim 1 provides a device for loading and unloading cargo oil in a tanker, in which one end is provided on the unloading side and the other end is provided on the tanker. a multi-jointed cargo oil transfer pipe formed bendably so as to face the cargo oil tank; and a multi-jointed cargo oil transfer pipe provided on the unloading side to guide the tip of the cargo oil transfer pipe into the cargo oil tank. a transfer pipe guide device that bendably supports the cargo oil transfer pipe; and a cargo handling device provided at the tip of the cargo oil transfer pipe for handling cargo oil in the cargo oil tank via the cargo oil transfer pipe. The invention of claim 2 also provides a cargo oil cargo handling device comprising a pump, and a ship body having a recovered oil tank; ,
A multi-jointed cargo oil transfer pipe is formed to be bendable so that the other end faces into the cargo oil tank of a stranded tanker. a transfer pipe guiding device that bendably supports the cargo oil transfer pipe to guide it into the cargo oil tank; This is a marine tanker rescue ship that is equipped with a cargo handling pump that carries cargo into the recovered oil tank via a cargo handling pump.

[0009]

According to the structure of claim 1, when cargo oil is unloaded from a moored tanker to the unloading side, the tip of the cargo oil transfer pipe is guided into the cargo oil tank of the tanker by the transfer pipe guiding device. The cargo oil in the cargo oil tank can then be transferred to the cargo oil transfer pipe and handled by a cargo handling pump.

[0010] As a result, the cargo oil in the tanker can be handled by the cargo handling device on the unloading side, and since the cargo handling pump for cargo handling is installed at the tip of the cargo oil transfer pipe, the water head equivalent to atmospheric pressure is reduced. Even if the cargo oil tank is deeper than the pressure, the cargo oil can be completely unloaded.

[0011] In this way, since the cargo oil in the tanker can be unloaded from the unloading side, the unloading device can be omitted from the tanker, and the cost of the tanker can be reduced.

[0012] Furthermore, since the space for installing the unloading device can be used as a space for loading cargo oil,
Tanker capacity can be increased.

On the other hand, according to the structure of claim 2, when rescuing a stranded marine tanker, the tip of the cargo oil transfer pipe is inserted into the cargo oil tank of the stranded tanker using a transfer pipe guiding device. After guiding, the cargo oil in the cargo oil tank is collected into the recovery oil tank using a cargo handling pump.

[0014] As a result, the amount of cargo oil in the stranded tanker can be reduced, so the stranded tanker can be floated away from the stranded area, and in the event that cargo oil spills from the stranded tanker, can prevent oil spills.

[0015] Furthermore, even if the unloading device of a tanker breaks down due to a reef, etc., the cargo oil in the tanker can be recovered and rescued.

[0016]
